What is this fixing or adding?
Currently in Python, threadpool only fires up new threads as actually required, so lowering the number of allowed workers in the threadpool does nothing currently. But that's an implementation detail I'd prefer to not rely on never changing. It's well possible threadpool spins up threads ahead of time in the future so it takes less time for them to be available, for example.
So I'd rather explicitly limit the amount ahead of time, since we know exactly how many we might need.
How was this tested?
